[Chameleon] popup from rectangle

[Paul Spencer]

Ken,

this is one of the things that I would like to fix.  For now, you have 
to manually edit MapDHTML.js.  Search for QUERY (upper case), you should 
see it in three places as part of a large if() structure ... and the 
name that your widget puts in NAV_CMD into this if structure to make 
MapDHTML avoid submitting for your widget.

In the near future, I will be rethinking how this works to make it the 
responsibility of the widget to submit the page instead of the MapDHTML

Cheers,

Paul
